A cyclist moves horizontally at 19 kmph. There is no wind and rain drops appear to him to fall at an angle of 10 deg to the vertical. Find the speed of the rain drops.Given answer is 59.71 kmph.

Dear Pinaki,

Since the speed of rain appears to be zero to the cyclist , this shows that their relative velocity is zero ,

Thus

horizontal component of velocity of rain =  velocity of cyclist,

thus speed of rain = 59.71 kmph

Best Of luck
